Thumb Peak is a small mountain in central Palawan, Philippines, and is the highest point in the Thumb Range. Like Mount Mantalingahan and Mount Victoria further south, Thumb Peak is part of the Mount Beaufort Ultramafics geological area, a series of ultramafic outcrops of Eocene origin that emerge in various parts of the island.

Palawan Province in Mimaropa, Philippines

Palawan, officially the Province of Palawan is an archipelagic province of the Philippines that is located in the region of MIMAROPA. It is the largest province in the country in terms of total area of jurisdiction. Its capital is the city of Puerto Princesa, but the city is governed independently from the province as a highly urbanized city.

Philippines Republic in Southeast Asia

The Philippines, officially the Republic of the Philippines, is an archipelagic country in Southeast Asia. Situated in the western Pacific Ocean, it consists of about 7,641 islands that are categorized broadly under three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. The capital city of the Philippines is Manila and the most populous city is Quezon City, both part of Metro Manila. Bounded by the South China Sea on the west, the Philippine Sea on the east and the Celebes Sea on the southwest, the Philippines shares maritime borders with Taiwan to the north, Vietnam to the west, Palau to the east, and Malaysia and Indonesia to the south.

Mount Victoria, Palawan mountain in Philippines

Mount Victoria, or Victoria Peaks, is a mountain in central Palawan, Philippines, that lies within the administrative Municipality of Narra. The mountain, which includes the twin peaks known as "The Teeth", as well as the single prominence known as Sagpaw, form the largest contiguous land area and second highest portion of the Mount Beaufort Ultramafics geological region, a series of ultramafic outcrops of Eocene origin, that includes Palawan's highest peak, Mount Mantalingahan.


The mountain was formerly known as Mount Pulgar, a name it acquired during the Spanish Colonial period. Pulgar, means thumb in Spanish, and the name was probably translated directly to English following the ousting of Spain during the Spanish–American War. The name may have arisen as a result of the mountain's profile, which vaguely resembles the tip of a thumb protruding from a clenched fist.

Spanish language Romance language

Spanish or Castilian, is a Western Romance language that originated in the Castile region of Spain and today has hundreds of millions of native speakers in the Americas and Spain. It is a global language and the world's second-most spoken native language, after Mandarin Chinese.

English language West Germanic language

English is a West Germanic language that was first spoken in early medieval England and eventually became a global lingua franca. Named after the Angles, one of the Germanic tribes that migrated to the area of Great Britain that would later take their name, England, both names ultimately deriving from the Anglia peninsula in the Baltic Sea. It is closely related to Frisian and Low Saxon, and its vocabulary has been significantly influenced by other Germanic languages, particularly Norse, and to a greater extent Latin and French.

Spain Kingdom in Southwest Europe

Spain, officially the Kingdom of Spain, is a country mostly located on the Iberian Peninsula in Europe. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta and Melilla make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean.

The upper reaches of Thumb Peak are populated by species associated with ultramafic soils, including a number of endemics, such as the tropical pitcher plant Nepenthes deaniana , rediscovered on the mountain in 2007 for the first time since its description in 1908 (see external links). [2]

Pitcher plant

Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar.

<i>Nepenthes deaniana</i> species of plant

Nepenthes deaniana is a tropical pitcher plant endemic to the Philippines, where it grows at an altitude of 1180–1296 m above sea level. The species is known only from the summit region of Thumb Peak, a relatively small, ultramafic mountain in Puerto Princesa Province, Palawan.

Hiking activity

Thumb Peak is accessible from the Iwahig Penal Colony as a 2–3 day hike, graded Difficulty 7/9 by local mountaineering website Highlights of the trail include river crossings, trekking through dense forests, and beautiful views at the summit. A permit is required to climb the mountain. [3]

Mount Guiting-Guiting mountain

Mount Guiting-Guiting is the highest mountain in the province of Romblon located at the heart of Sibuyan Island and dominates the entire island. Guiting-Guiting, in the local Romblomanon dialect, means "jagged". The mountain is one of the focal points of Sibuyan's declaration as a biodiversity haven. The entire island has been compared numerous times with the biodiversity endemism rate of the Galapagos islands. This endemism prompted much of the mountain and its slopes to be protected under the Mt. Guiting-Guiting Natural Park, established in 1996. The park also encompasses nearby Mt. Nailog to the west.
